Classic rockers, this one’s for you: It’ll be a Sunday in the park, and not quite the Fourth of July, but Chicago’s coming back to the Austin360 Amphitheater on July 1, and they’re bringing REO Speedwagon along with them. (Perhaps the Speedwagon can take a few laps on the Circuit of the Americas track while they’re out there.)

Between them, the pair of Illinois bands were huge on rock radio in the 1970s and ’80s. Just when Chicago’s brass-heavy sound that brought the likes of “25 or 6 to 4” and “Saturday in the Park” to prominence began to fade, REO Speedwagon’s anthemic hooks became omnipresent with smashes such as “Take it On the Run” and “Keep on Lovin’ You.”

It’s a fairly quick return trip for Chicago, which played the same venue last June as part of its 50th-anniversary tour with opening act the Doobie Brothers. REO Speedwagon also was here last summer, but they played the HEB Center at Cedar Park with Styx on that tour. Their last performance at Austin360 Amphitheater was in August 2016 with Def Leppard and Tesla.
